AXIS 213 PTZ

Bandwidth

As there are many factors affecting bandwidth, it is very difficult to predict the required amounts. The

settings that affect bandwidth are:

• the image resolution

• the image compression

•the frame rate

• the MPEG-4 object type

• the MPEG-4 GOV structure

• the audio settings

There are also factors in the monitored scene that will affect the bandwidth. These are:

• the amount of motion

• the image’s complexity

• the lighting conditions.

For MPEG-4, if there is only limited bandwidth available, and if this is more important than the image

quality, using a constant bit rate (CBR) is recommended. Use a variable bit rate (VBR) if the image quality

needs to be maintained at a higher level. If supported on the network, consider also using MPEG-4

multicasting, as the bandwidth consumption will be much lower.
